# PT-4(1) Tailored Consent

> **Enhancement of:** PT-4

## High-Level Description

**Family:** Personally Identifiable Information Processing and Transparency (PT)
**Framework:** NIST SP 800-53 Rev 5

While some processing may be necessary for the basic functionality of the product or service, other processing may not. In these circumstances, organizations allow individuals to select how specific personally identifiable information elements may be processed. More tailored consent may help reduce privacy risk, increase individual satisfaction, and avoid adverse behaviors, such as abandonment of the product or service.

## What to Check

- [ ] Verify PT-4(1) Tailored Consent is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for PT-4(1)
- [ ] Verify enhancement builds upon base control PT-4

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for PT-4(1) implementation details. Verify the organization has documented how this control is satisfied.

### Step 2: Validate Implementation

```
# For cloud environments, use cloud-audit-mcp tools
# For on-premises, review system configurations directly

# Example: Check if account management policies exist
grep -r "account.management\|access.control" /etc/security/ 2>/dev/null
```

### Step 3: Test Operating Effectiveness

Verify the control is actively functioning, not just documented. Check logs, configurations, and operational evidence.
